Small-scale hard rock miners do not have the luxury of a fully equipped industrial-grade mill with flotation and cyanide leaching to process their ore and recover values. We are usually limited by practicality, finances and permitting to a simple crushing and grinding circuit, with a gravity recovery system for the free milling values and value ...

DEFINITION OF HARDROCK MINING TERMS Adit - A level, horizontal drift or passage from the surface into a mine. Borehole - A vertical or inclined hole, used for ventilation from one level to another, or to carry waterlines or electrical wires. May be large enough for a man to climb through, but much smaller than a raise.

1 The demand for mineral resources has dramatically increased over the past few decades; this increase directly correlates to an increase in underground mining activity. There are different mining methods for different minerals, and each have their risks. In hard rock mining activities such as mining for gold, rockfalls are the most significant deterrent to obtaining mineral …

Block caving is an underground hard rock mining method that involves undermining an ore body, allowing it to progressively collapse under its own weight. It is the underground version of open pit mining. In block caving, a large section of rock is undercut, creating an artificial cavern that fills with its own rubble as it collapses.

Lithium Mining. Talking about a mine in the lithium mining site, we first imagine a cave-like tunnel in the earth where workers excavate rock and rare earth ores with pickaxes and heavy diggers. But in mining lithium a slightly different process is preffered. Lithium has historically been produced from two sources: brines and hard rock mining.

The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.
